After seeing that academics still have to take a “two job” approach with serious research and fun research I’m not convinced of this. Not to mention the very protracted timelines to get to that stage of freedom.
After PhD there will be nobody telling, and often not even caring, what to do. But that may mean that you don't get your PhD or you don't get another grant to live on. If you get a tenure it almost literally means that you can't be fired even if you do nothing at all. What is surprising is that almost all with tenure keep running the rat race even though they don't really get anything at least material out of it.
(Nitpick: I think serious research is the fun one. The one churned to get another grant is neither serious nor fun.)

If you make the hiring cut in you’re in for about 5 years of grunt work and committees as an assistant prof, right?
By “serious research” I mean the one they do for career advancement and hiring.
I am a postdoc, just have been for quite a while (on four different grants at least). In Finnish academia it's not that uncommon to stay a postdoc even until retirement.

For teaching and admin yes. But at least in fields I know, what research you do or whether you do at all is all up to you. Of course the risk is that you'll be unemployed after the assistant prof. term ends. My point is that if you don't care about that, you're quite free to do whatever research-wise.
